Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a powertrain mounting structure. Background Technology

[0002] The powertrain mounting structure of an electric vehicle is a key component that connects the powertrain to the subframe or body. It includes rubber mounts, hydraulic mounts, cylindrical bushing mounts, etc. Among them, the rubber mount is usually composed of a rubber bushing and a metal bracket. The rubber bushing is the core component and is generally designed to be a near-solid structure.

[0003] In existing technologies, rubber suspension structures in electric vehicles are mostly fixed to the vehicle frame by bolts. When the rubber suspension structure needs maintenance or replacement, the disassembly process is relatively complicated because it is fixed to the vehicle frame by bolts. This is because technicians need to spend more time disassembling and assembling each bolt, which increases maintenance time and makes installation and disassembly maintenance inconvenient.

[0004] Therefore, it is necessary to propose a powertrain mounting structure to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a powertrain mounting structure that can effectively solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A powertrain mounting structure includes a subframe and a mounting plate bolted to the edge of the subframe surface. L-shaped plates are symmetrically fixed to the upper surface of the mounting plate. Mounting grooves are equidistantly spaced on the surface of the L-shaped plates. A mounting bracket is located in the center of the upper surface of the mounting plate. An annular block is symmetrically fixed to one end of the mounting bracket near the bottom. Rotating plates are slidably inserted into the walls of multiple mounting grooves. Rotating columns are symmetrically rotatably connected to the surface of the rotating plates. A column groove is formed on the surface of the rotating column. A T-shaped column is slidably connected to the wall of the column groove. A first spring is fixed to one end of the T-shaped column located within the column groove. An L-shaped block is fixed to the other end of the T-shaped column. A limiting mechanism for limiting the installation of the mounting bracket is provided between two L-shaped blocks.

[0008] Preferably, the upper surface of the mounting plate is symmetrically fixedly connected with limit strips next to the suspension bracket.

[0009] Preferably, the mounting groove wall is slidably connected with protrusions, and multiple protrusions are fixedly connected to the rotating plate.

[0010] Preferably, the limiting mechanism includes a cylinder fixedly connected between two L-shaped blocks, an annular block sleeved on the middle of the surface of the cylinder, a circular groove evenly distributed in a ring on the surface of the annular block, a T-shaped rod slidably connected to the wall of the circular groove, a second spring sleeved on the outer side of the T-shaped rod, an adjusting block fixedly connected to one end of the three T-shaped rods away from the circular groove, two adjusting blocks slidably connected to the cylinder, and a limiting groove evenly distributed in a ring on the surface of the L-shaped block next to the cylinder, the multiple limiting grooves being installed in conjunction with the adjusting blocks.

[0011] Preferably, the second spring is initially in a compressed state.

[0012] Preferably, the limiting groove wall is slidably inserted with a locking block, and multiple locking blocks are fixedly connected to the adjusting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This powertrain mounting structure, through the engagement of a rotating plate and a mounting groove, and the engagement of a limiting groove and a locking block, limits the installation of the mounting bracket, avoiding the need for bolt-fixed connection between the mounting bracket and the mounting plate. During installation, simply hold each of the four adjusting blocks with both hands to separate the limiting groove from the locking block. Move the T-shaped rod to the other end of the circular groove, allowing relative rotation between the annular block and the cylinder. Align the protrusions on the rotating plate surface with the mounting groove. Once the bottom of the mounting bracket contacts the surface of the mounting plate, simultaneously release the four adjusting blocks. Under the action of the second spring, the locking block engages with the limiting groove, limiting the installation of the mounting bracket. For disassembly, similarly adjust the four adjusting blocks to separate the locking block from the limiting groove, then lift the mounting bracket away from the mounting plate. This optimizes the installation and disassembly steps between the mounting bracket and the subframe, shortens maintenance time, improves maintenance efficiency, and facilitates the installation and disassembly of the mounting bracket and subframe.

[0015] 2. The powertrain mounting structure has multiple mounting slots, and the mounting bracket can be adjusted to fit the mounting plate according to the actual usage. It can be flexibly installed according to the specific characteristics of the powertrain. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a powertrain mounting structure includes a subframe 1 and a mounting plate 2 fixedly connected to the edge of the surface of the subframe 1 by bolts. An L-shaped plate 3 is symmetrically fixedly connected to the upper surface of the mounting plate 2. Mounting grooves 4 are equidistantly formed on the surface of the L-shaped plate 3. A mounting bracket 5 is provided in the middle of the upper surface of the mounting plate 2. An annular block 6 is symmetrically fixedly connected to one end of the surface of the mounting bracket 5 near the bottom. Rotating plates 7 are slidably inserted into the walls of multiple mounting grooves 4. Rotating columns 8 are symmetrically rotatably connected to the surface of the rotating plates 7. A column groove 10 is formed on the surface of the rotating columns 8. A T-shaped column 11 is slidably connected to the wall of the column groove 10. A first spring 12 is fixedly connected to one end of the T-shaped column 11 located in the column groove 10. An L-shaped block 13 is fixedly connected to the other end of the T-shaped column 11. A limiting mechanism 9 for limiting the installation of the mounting bracket 5 is provided between two L-shaped blocks 13.

[0024] The upper surface of the mounting plate 2 is symmetrically and fixedly connected to the limit strip 14 next to the suspension bracket 5;

[0025] It should be noted that the setting of the limit strip 14 can limit the L-shaped block 13 after adjustment, and prevent the suspension bracket 5 from shifting position after it is installed with the mounting plate 2.

[0026] The mounting slot 4 has protrusions that slide into the slot wall, and multiple protrusions are fixedly connected to the rotating plate 7.

[0027] It should be noted that the protrusion cooperates with the mounting groove 4 to limit the installation of the suspension bracket 5, avoiding the use of bolts for fixed connection, thus facilitating the disassembly and assembly of the suspension bracket 5 and the mounting plate 2.

[0028] The limiting mechanism 9 includes a cylinder 91 fixedly connected between two L-shaped blocks 13, an annular block 6 sleeved on the middle of the surface of the cylinder 91, a circular groove 92 evenly distributed in an annular pattern on the surface of the annular block 6, a T-shaped rod 93 slidably connected to the groove wall of the circular groove 92, a second spring 94 sleeved on the outer side of the T-shaped rod 93, an adjusting block 95 fixedly connected to the end of the three T-shaped rods 93 away from the circular groove 92, both adjusting blocks 95 slidably connected to the cylinder 91, and a limiting groove 96 evenly distributed in an annular pattern on the surface of the L-shaped block 13 next to the cylinder 91, and multiple limiting grooves 96 are installed in cooperation with the adjusting blocks 95;

[0029] It should be noted that by simply pinching the four adjusting blocks 95 with both hands to separate the limiting groove 96 from the locking block, the T-shaped rod 93 moves to the other end of the circular groove 92, and the annular block 6 and the cylinder 91 can rotate relative to each other. Then, align the protrusion on the surface of the rotating plate 7 with the mounting groove 4. When the bottom of the suspension bracket 5 contacts the surface of the mounting plate 2, release the four adjusting blocks 95. Under the elastic force of the second spring 94, the locking block and the limiting groove 96 cooperate to limit the installation of the suspension bracket 5, thus completing the installation. When disassembling, adjust the four adjusting blocks 95 to separate the locking block from the limiting groove 96, and then lift the suspension bracket 5 away from the mounting plate 2. This optimizes the installation and disassembly steps between the suspension bracket 5 and the subframe 1, shortens the maintenance time, improves maintenance efficiency, and facilitates the installation and disassembly between the suspension bracket 5 and the subframe 1.

[0030] The second spring 94 is initially in a compressed state;

[0031] It should be noted that the reaction force generated by the compression of the second spring 94 acts on the surface of the adjusting block 95, so that the locking block on the surface of the adjusting block 95 can stably cooperate with the limiting groove 96, thereby ensuring the stable installation between the suspension bracket 5 and the mounting plate 2.

[0032] The wall of the limiting groove 96 is slidably connected with a locking block, and multiple locking blocks are fixedly connected to the adjusting block 95.

[0033] It should be noted that the locking block can cooperate with the limiting groove 96, thereby limiting the rotation of the annular block 6. After the suspension bracket 5 is installed, it can ensure the stability of the suspension bracket 5. The installation and disassembly between the suspension bracket 5 and the mounting plate 2 can be carried out by simply adjusting the locking block to cooperate with or separate from the limiting groove 96.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
